[5.2] Add after and before to dependent rules array

[themsaid]

Fixes #11648 (comment)

[vlakoff]

The 4 tests you added here fail on my computer ("Failed asserting that false is true")

[vlakoff]

Not really familiar with the code here, @themsaid do you have an idea what could be the cause of this platform discrepancy?

[themsaid]

@vlakoff hmmmm, it's hard to say. I think you'll need to trace the issue in validateAfter and validateBefore to see why they're failing, maybe it's related to using the year 2046 in the tests, but not sure at all.

[vlakoff]

Good catch, I tested on a 32-bit PHP. Will check this.

[vlakoff]

Yep, that's it.

Max working value is 2038-01-19, as we will be very sad at 03:14:07 UTC on 19 January 2038 (that's only 22 years!).

Do you want to PR this?

[themsaid]

Yup, I don't even know why I used 2046 :D It was totally random, maybe it's a sign something will happen that year, hopefully something good.

I'll fix that :)
